Learn how to create interactive 3-D animations with Alice, a versatile tool inspired by Alice in Wonderland for beginners and experts. Explore movie and interactive animations, create new worlds, add objects, and save your creations. Discover techniques and tools to enhance your animation skills.
E N D
Obj: Introduction to Alice Alice is named in honor of Lewis Carroll’s Alice in Wonderland
Alice • A modern programming tool • 3-D graphics • 3-D models of objects • Animation • Objects can be made to move around the virtual world (a video game or simulation implemented in 3-D) • Can download latest version from the web www.alice.org
Demo: Getting started • Starting Alice • Load and run a world • Octopus (movie) • Skater (interactive)
Kinds of Animations • Two kinds of animations: • Movie • Passive user watches the animation • Interactive • Active user clicks on mouse, types a key on keyboard … • Actions of user are called events
Demo: A new world • Create a new world • File New • Choose template
Techniques and Tools • Mouse is used to • approximately position objects in the scene • Camera Navigation is used to • set the camera point of view • Drop-down menu methods are used to • resize objects • more precisely position objects in the scene • Quadview is used to • position one object relative to another object
Objects • An "object" is • any thing that can be identified as unique from other things • How is an object unique? • has a name • has properties: • width, height, color, location • can perform actions (methods): • associated actions it can perform • tasks it can carry out
Object Parts • Objects may be composed of parts
3 Dimensions, 6 Directions • A 3D object has • 3 dimensions • height, width, depth • 6 degrees of freedom (directions of movement)
Center of an object • At the center of mass • Where it stands on the ground • Where it is held
peter Person paul mary spike Dogs scottie fluffy Class • Objects are categorized into classes • Each object is an instance of the class. • All objects in a class have similar propertiesand generally can perform the same tasks.
Galleries • Classes (3D models) are found in the galleries • Local gallery (installed with the software) • Minimum or complete options • CD Gallery (only if CD is in the machine) • Web gallery
Demo: Saving a world • Writing and testing an animation is an intense load on the computing system – a crash can occur. • Best solution: • save your world every 15 minutes • (Or at least every half hour) • also save to a backup system (for example, a zip disk or memory key)
Assignment • Read (before the next class session) Chapter 1 • Section 1, Introduction to Alice • Section 2, Alice Concepts • Tips & Techniques 1, Special Effects
Lab • Appendix A, Getting Started – Parts I & II • Exercises from Chapter 1 • Notes: • Lab exercises and projects require that you demonstrate the code and execution of your programs to the instructor or the TA • Your lab sheet must have the signature of the instructor or TA for each assigned exercise and/or project. Otherwise, you will not get credit for having completed the lab!
